Description

The installation method of storage tank inversion lifting fastening packing
Technical field
The present invention relates to a kind of installation method of the hoisting tool for storage tank inversion, specifically a kind of storage tank falls The installation method of dress method lifting fastening packing.
Background technology
At present, upside-down method of hull-section construction is the conventional installation method of large and medium-sized storage tank, and upside-down method of hull-section construction is first to install tank deck, from most upper band Wallboard is installed by band downwards, finally welded with bottom plate.Upside-down method of hull-section construction exists all the time as a kind of safety and efficient mount scheme Large-scale steel structure storage tank installing area is widely used, and in the welding process of storage tank inversion, can typically pass through volume Raising machine drives the packing for being welded on inner tank wall face to rise, so as to drive tank body to be lifted up.Packing is carrying as aid Ensure to play an important role in circularity during liter tank body, tank shell girth welding, but existing packing is due to being welded on On top tank structure, the welder that need to be used when tank body is installed is more, wastes substantial amounts of manpower, virtually adds installation cost, And installation effectiveness is not also high.In addition, the packing of prior art is due to being welded in inner tank wall, it is impossible to tank body is produced obvious Radial direction expansive force, result in tank body welding, it is impossible to the effective circularity for ensureing tank skin in welding process.
The content of the invention
A kind of installation method it is an object of the invention to provide storage tank inversion with lifting fastening packing, it is existing to solve Storage tank inversion installation cost present in packing installation method is high, installation effectiveness is low and and cannot be guaranteed tank in welding process The problem of circularity of wall.
The object of the present invention is achieved like this:A kind of installation method of storage tank inversion lifting fastening packing, including Following steps:
A, according to the equal arc packing monomer of the internal diameter sectional making multistage arc length of tank body to be hoisted:Every section of packing Monomer is bent for square hollow square tube by section and formed, and the external diameter of the packing monomer is equal to the internal diameter of tank body, in every section of institute The both ends for stating the outer ring surface of packing monomer are symmetrically welded with suspension ring for being connected with hoist engine;
B, in the same level at the middle part of the internal face of tank body uniform welding have it is multigroup be used for support the packing list The packing bracket of body, the quantity of packing bracket is equal with the quantity of packing monomer, and packing bracket described in every group includes two packings Supporting plate, the arc length between two packing supporting plates of every group of packing bracket are less than the arc length of every section of packing monomer, the welding of packing bracket After packing monomer is correspondingly placed on packing bracket using hoist engine, the distribution of two packing supporting plates of every group of packing bracket At the both ends of corresponding packing monomer bottom;
C, the connection of arc packing monomer is circularized into packing:Prepare to be used to connect phase with the packing amount of monomer identical The sliding connection plate of packing monomer described in adjacent both ends, sliding connection plate is curved plate, outside each sliding connection plate Footpath is equal to the internal diameter of packing, and the sliding connection plate fitting is arranged on the connection of the inner ring surface of the packing monomer of adjacent two Place, the end of the sliding connection plate and the corresponding end of the packing monomer are slidably connected, and whole sliding connection plates installs Packing monomer is assembled into annular packing after finishing;
D, hydraulic jack is fixedly connected between the packing monomer and adjacent packing monomer, by hydraulic jack Oil circuit is connected on the hydraulic station used in hoist engine, and the synchronous whole hydraulic jacks of unlatching are swollen by annular packing and inner tank wall Tightly;
E, all suspension ring on the annular packing are connected with hoist engine simultaneously, it is swollen opens the hoist engine lifting annular Circle is to drive the lifting of tank body, until tank body is placed into required position;
F, the end of hydraulic jack is retracted so that annular packing and reservoir walls after the annular packing use Separation, then taken out annular packing in case next time uses with hoist engine.
The hydraulic jack is bidirectional hydraulic jack.
The method that sliding connection plate is slidably connected with the packing monomer in step c is:In each sliding connection plate The upper and lower part of both sides along the circumferential direction is provided with strip chute, is opened in the end of the inner ring surface of every section of packing monomer There is the threaded connection hole corresponding with strip chute, prepare what is matched with threaded connection hole number identical and with threaded connection hole Slide bolt, slide bolt sequentially pass through threaded connection hole and the strip chute by the inside of the packing monomer, and in cunning The tail end of dynamic bolt is screwed into nut, and the head of the slide bolt is arranged on the inside of the packing monomer.
The present invention is fixedly connected with hydraulic jack between packing monomer and adjacent packing monomer, by hydraulic jack Oil circuit is connected on the hydraulic station used in hoist engine, synchronous to open whole hydraulic jacks by all annular packings and inner tank wall Swelling, in the presence of expansive force, tank body can be driven to raise together when packing is lifted, both eliminate the process of welding, saved Labour, and can enough ensure the circularity of tank body.And it can be quickly removed after this section tank body installs and be applied to lower section tank The use of body, improves installation effectiveness.
The present invention is flexible to operation in fliping lifting engineering and substantially increases lifting by the cooperation with hoist engine Efficiency, shorten the duration, reduce construction cost, largely improve storage tank inversion construction quality, effectively The appearance and size of tank body is ensure that, is avoided because of the tank body local dent caused by lifting force phenomena such as.
